Be it known that I, CHARLES RINOK, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Steam-Boilerliurnaces; an I do hereby d following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to shall be distributed over or be thoroughly difducts which it appertains to make and use the same. from the burning mass. My invention relates to that class of steam The fines may be arranged differently than boiler furnaces wherein steam and air are inas above described only so that they sha l isjected onto or over the mass of burning fuel. i charge into or from the front of the furnace. My invention consists in injecting steam Connected to the dome, I, of the boiler, are gas, or superheated air,in a mingled or mixed steam pipes J, which exten down therefrom state, onto or over the burning mass or into and communicate with asteam-box or coil,l the flame, and in causing the mingled gases located in this instance at the top of the bridge to pass under, or be acted upon, by a reverwall and to which box or coil is connected a beratoryarchtoforcesuchmingledgasesdown steam pipe, J, which extends therefrom to upon or into the highly heated fuel, whereby and around the front of the furnace and havto insure perfect combustion of the otherwise ing branch pipes or nozzles, J opening into wasted or unconsumed products, and to certhe discharge outlets from the air dncts,formtain novel features in the construction and ar- 1 ing an injector to draw the air into the dues rangement of parts, all as hereinafter exto be mingled therewith and with the rising lained, illustrated in the drawings, and spegases from the burning fuel and by which to cifically pointed out in the claim. insure the mingling therewith of a proper In the accompanying drawings, wherein amount of oxygen and steam gas in a finely likeletters of reference point out similar parts divided state to secure the proper and perfect on each figure:-Figure 1, is a vertical longicombustion of the same.
